Does anyone know where I can download a parts or assembly diagram for a Mossberg 9200? I have one I think may have been assembled the wrong way when it was last cleaned. My buddy says it won't autoload a shell after the first shot. It looks fine to me but I don't know anything about the 9200's. It is dirty as can be too. Actually, I can't believe the thing will even fire at all, it's that dirty.

Thanks, Jon Foster.
